Tata Hexa
Coolant capacity & service interval
Tata Hexa coolant capacity is 9 liters. Service intervals include checking every 10000 km or 6 months and changing every 60000 km or 36 months. The data covers 6 configurations.

Additional Notes
- All Tata Hexa configurations listed — the 2.2 Varicor in 110 kW and 115 kW outputs, including the AWD variant — share an identical cooling system capacity of 9 liters across the 2017-2020 period.
- A 9-liter cooling system capacity is consistent with a larger displacement diesel engine in a body-on-frame SUV, where the cooling circuit includes the engine block, cylinder head, heater core, and expansion reservoir volume.
- The check interval of 10,000 km or 6 months, whichever comes first, applies under normal use conditions across all six configurations and is separate from the full coolant change schedule.
- Periodic coolant checks at 10,000 km or 6-month intervals serve to monitor concentration, pH level, and coolant volume without requiring a full drain and refill of the system.
- The coolant change interval is set at 60,000 km or 36 months under normal use conditions, meaning a full drain, flush, and refill of the 9-liter system is due at whichever of those two thresholds is reached first.
- A 36-month change interval for coolant reflects a standard long-life formulation, where the corrosion inhibitors and antifreeze properties are rated to remain effective within that time and distance window under normal operating conditions.
- The 110 kW and 115 kW variants of the 2.2 Varicor engine share the same 9-liter cooling system capacity, indicating the cooling circuit architecture is common between the two power outputs despite the difference in engine tune.
- The AWD variant of the 115 kW Hexa carries the same 9-liter coolant capacity and identical service intervals as the two-wheel-drive 115 kW version, showing the addition of all-wheel-drive hardware does not alter the engine cooling system specifications.
